Forecast for Puerto Madryn on August 20th, 2025: What does the weather hold?

Prepare for a chilly visit to Puerto Madryn, Argentina, as August brings cool temperatures and clear skies. Here's what you need to know for your trip.

On August 20, the weather in Puerto Madryn will be partly cloudy in the morning with temperatures around 5 degrees. The sun will rise at 08:07, and by midday, the temperature is expected to rise to 15 degrees. Sunset will be at 18:41, with temperatures dropping to around 9 degrees in the evening.

It's essential to dress appropriately for the low temperatures, so pack warm clothing. The average temperature range in Puerto Madryn during August is typically cool, with daily highs around 10°C to 12°C and lows close to 8°C to 9°C.

The nearby Puerto Pirámides area, known for its cool sea water temperatures, has averages from 8.8°C to 12.4°C in August, indicating overall cool air temperatures as well. Inland daytime temperatures in Patagonia coastal areas like Puerto Madryn in winter (June–August) generally hover around 10°C, with nighttime lows potentially lower but usually above freezing.

To stay safe during your visit, it's crucial to take precautions against cold weather. Avoid prolonged outdoor exposure without appropriate clothing, as cold can cause hypothermia or frostbite. High-altitude or wind-exposed hiking or trekking without proper gear should be avoided due to the risk of cold-related injuries and hypothermia.

It's also important to avoid water activities like swimming or sea kayaking when sea temperatures are very low (around 9–12°C), as cold water immersion risks hypothermia quickly. Strenuous outdoor physical activity without a warm-up and proper layering can strain cardiovascular health in cold weather.

In general, avoid activities that increase the risk of slipping or falling in icy or frosty conditions. Additionally, it's recommended to drink plenty of hot liquids and reinforce hygiene norms to prevent the spread of diseases like the flu in extreme low temperatures. Also, ventilate the indoor environments to avoid inhaling carbon monoxide in extreme low temperatures.

Stay informed by the authorities in extreme low temperatures, and remember that the weather in Puerto Madryn on August 20 will be dry with south winds blowing at speeds between 23 and 31 kilometers per hour. In the evening, winds from the north will be blowing at speeds of 7 to 12 kilometers per hour. The humidity in Puerto Madryn will be 37%.

With these tips in mind, you're ready to enjoy a cool, yet exciting visit to Puerto Madryn this August.
